I was brought up mostly by foster care and group homes I spent about 4 years of my childhood with my biological mother. I reconnected with her as a young teen but I did not expect any perfection. Oh and in case you are wondering, my father abandoned my mother and I about three months before I was born. I don't think your upbringing is as relevant to your religious or non-religious beliefs later in life. Not everyone takes the same path in life and reach the same conclusions.
There is nothing people will not maintain when they are slaves to superstition
